Once again I have only praise for it.
When I had a query with Spitfire it took over a week to get a reply.
Last night a VSL update was messed up. The host software seemed to be lost. It brought me to a standstill. I emailed VSL support with such details as I could hoping for a reply today.
Anyway it seems that a couple of Windows programs had got lost. Ha! Not being a technical person I couldn't have worked that out by myself. None of the error messages gave a clue. But VSL did and directed me to the MS site to download them and suggested I re-did the update.
Everything's working again fine.
Point is, I wrote at 6pm. The reply came back at 7.15pm.
Not the first time this has happened.
